Definitions

  • the present invention relates to a device for unscrewing threaded plastic plugs usually applied to bottles, in accordance with the preamble of claim 1.
  • plastic plugs are used for various utilizations, particularly to cork glass or plastic bottles.
  • a cap remover tool of the type described in the prior art portion of Claim 1 (US-A 4,509,784) is known in which the cap remover includes a split ring and a pair of handles to actuate the split ring.
  • the tool of this kind has the disadvantage of concentrating the compression on two opposite points of the cap. As a consequence, a cap of plastic material could be so deformed as to cause a not correct grasp between the cap and the threaded neck of the container during the screwing and the unscrewing operations. Morevoer, this kind of cap remover is provided with protruding and opposite stop shoulders that could disadvantageously act as a fulcrum for breaking stresses of the hinge of the handles.
  • the object of the present invention is to obviate to the difficulties and drawbacks above mentioned.
  • the device 1 that is the object of the present invention is fundamentally constituted by an elongated element 11 shaped in the form of a handle and an annular element formed as a cylindrical ring 12 extending from one end of said handle.
  • Said ring 12 is interrupted for a discrete length along its circumference so that the free end of said ring is adjacent to said one end of the handle 11.
  • a curved element 13 is formed at the free end of said ring 12 so as to extend in a direction opposite to said handle and to form a trigger.
  • figure 1 shows that the internal concave part 131 of the curved element 13 is connected to the external edge of said cylindrical ring 12 with a suitably radiated lenght 132.
  • the internal surface of said cylindrical ring 12 is moreover suitable notched by a plurality of light indentations 14 able to engage themselves in the corresponding indentations that usually are executed on the external cylindrical surface of the plugs.
  • first reducing ring 22 is illustrated in inserted position while the second reducing ring 32 is illustrated in external position before the insertion in the previous.
  • Both said reducing rings 22 and 32 obviously are interrupted along their circumference in such a way as to present a relative discrete interruption length, respectively T1 and T2.
  • the inside surfaces of said reducing rings 22,32 will be suitably notched as the cylindrical ring 12 by relative pluralities of light indentations respectively 24 and 34, moreover preferably from one of the lateral edges of each of such reducing rings 22,32 a little flange, respectively 25 and 35 will protrude outwards
  • the cylindrical ring 12 will have a radial fairly thin thickness equal to about the half of its length in axial direction (pratically about mm 4) so as to obtain a sufficient mechanical resistance of the same as well as a suitable elastic deformation and the radial thicknesses of the said reducing cylindrical rings 22,32 will also be fairly thin (about mm 3) so as to permit a suitable elastic deformation.
  • the said first and second reducing rings 22 and 32 have an external diameter equal respectively to the internal diameter of the cylindrical ring 12 and of the first reducing ring 22 so that the first reducing ring 22 can be inserted in the cylindrical ring 12 and the second reducing ring 32 can be inserted in its turn in the previous first reducing ring 22.
  • the flanges 25 and 35 of the reducing rings 22-32 have the function to stop the insertion of the latter in the correct position of application preventing so that they get out from the part opposed to the utilization part, moreover the insertions will happen with a suitable interference so that the said reducing rings 22 and 32, when applied, remain fixed even if they can be easily taken out.
  • the internal circular edges 121 of the cylindrical ring 12 as well as the external 222,322 and internal 221,321 circular edges of the reducing rings 22,32 are chamfered in order to facilitate the mutual insertion of said rings 12,22,32 into each other as well as the insertion in them of the plugs to be unscrewed.
  • the device 1 and the relative reducing rings 22 and 32 will be obtained by simply molding of a suitable plastic material.
  • the user first of all will adapt the device to the plug to be unscrewed. To do this operation, if the diameter of the plug coincides or is fairly smaller than the diameter of the cylindrical ring 12, the user will take away both the reducing rings 22-32 and will insert the said cylindrical ring 12 on the plug then will grip the element 11 putting the index finger in the internal concave part (131-132) of the element 13.
  • the user will insert the first reducing ring 22 and eventually also the second reducing ring 32 until he reaches the external diameter of the plug in question and then will proceed to effect the unscrewing of it in the way above described.
  • the said reducing rings 22 and 32 can run reciprocally in circle between themselves as well as to the cylindrical ring 12 that contains them so that practically the clamping force R does not appreciably increase.
  • the said reducing rings 22 and 32 can run reciprocally, they can be applied placing them with their interruption lenght T1 and T2 in every position, moreover given the symmetriy of the opposite faces of the device 1 and particularly of the hole of its cylindrical ring 12, the insertion in it of the said reducing rings 22 and 32 can happen by both the parts and moreover the same device 1 can be applied on the plug to be unscrewed in two symmetrically opposite ways permitting so to be used advantageously also by left-handers.
  • the device 1 that is the object of the present invention clearly permits to obtain not only the remarkable advantage to effect the unscrewing of the plugs from relevant bottles when they are fixed in such a way that they can't be taken away using only the hands but also to permit to do such operation on plugs having various diameters.
  • the diameter of the cylindrical ring 12 in the shape of realization to which it is done reference is of about mm 32, and can be increased so as to permit the use of the device 1 on plugs having greater diameters, moreover the number of the reducing cylindrical rings can be greater than the one expounded permitting so to increase the diameter range of the plugs on which it will be possible to operate.
